推荐答案

获取所选图像的图片ID然后使用意图图片ID传递给FullImage活动。该活动使用ImageView的显示图像。

Get image Id of selected image then pass that image id to FullImage activity using Intent. Display image in that activity using ImageView.

遵循编码像这样

活动1 //其中图像可用。

Activity1 // where images are available..

Intent fullScreenIntent = new Intent(v.getContext(),Full.class); 
fullScreenIntent.putExtra(Full.class.getName(),imageId);

在FullImage Activity..add这种编码。

in the FullImage Activity..add this coding.

int imageId1 = intent.getIntExtra(Full.class.getName(),default1); 
InputStream is = this.getResources().openRawResource(imageId1);
Bitmap originalBitmap = BitmapFactory.decodeStream(is);
ImageView myimage = (ImageView) findViewById(R.id.ImageView01);
myimage.setImageBitmap(originalBitmap);
myimage.setScaleType(ScaleType.MATRIX);
